SPLICING OF PRECAST PRESTRESSED CONCRETE PILES: PART I-REVIEW AND PERFORMANCE OF SPLICES

Effective splicing of prestressed concrete piles can reduce or eliminate many problems associated with the installation of long piles. Proper splicing methods eliminate the need to predict precise pile lengths, and allow extensions of piles when necessary. This report presents the results of an investigation into existing methods presently used in the splicing of prestressed concrete piles. The first part of this report constitutes a review and evaluation on splicing methods developed and used in several areas of the world. The second part of the report, to be published in the next issue of the PCI JOURNAL, describes actual tests and analyses of one of the splices described in this article.
